Show HN: Make your logo extra bright on HDR screens

Certain logos started standing out to me on LinkedIn as brighter/whiter than everything else around them.

I dug in and found out this is accomplished by adding a gain-map to an existing JPEG, visible only on HDR screens like a newer MacBook Pro. LinkedIn is the only social network I've found that isn't stripping them out, but of course you serve them up on your own site.

I worked with Claude Code to turn it into a little browser-based utility (no registration) and hope you find it useful!
